The original Stratos was mechanically a Ferrari, so little difference, really. I'd love to think they would run it in tarmac rallies, in full alitalia colours...
I have VERY fond memories of Markku Alen attacking the RAC Rally in HALF a Stratos, after the boot lid flew off somewhere in Sutton Park! That noise rattling of trees sends shivers down the spine, even now.
A real one competes in rallies in the UK, sponsored by Vodka Kick.

It took a LOT of aero kit to turn it into a circuit racer, though...
